San Francisco's incredible effort was paced by Ryan Vogelsong's dominant pitching performance. The Giants' starter went seven innings, allowing one run on four hits and setting a new career-high in strikeouts with nine. He was mixing his pitches well, using his command to keep St. Louis off-balance for the duration of his start.
Adding to that effort was Chris Carpenter's poor performance. The Giants touched him up for six hits and two earned runs. Part of his struggles were due to Pete Kozma's error in the second inning, but he also pitched himself into jams throughout his short four-inning start.
The Giants used perseverance, pitching and an excellent second inning to force Monday's Game 7. Vogelsong's performance would have been for nothing if it hadn't been for Marco Scutaro's double to deep left in the second, followed by Pablo Sandoval's RBI single after that.
Once Vogelsong was lifted, Jeremy Affeldt and Santiago Casilla were able to combine on a shutout eighth inning, giving the ball to Sergio Romo with a five-run lead.
Romo took the mound in the ninth, threw eight pitches and struck out one batter to close out the game.
With the Giants win Sunday night, it all comes down to Kyle Lohse and Matt Cain in Monday's Game 7. It's win or go home, with a World Series berth on the line.
